I've tried a number of workout logging apps and Strong is easily the best I've used by a long way. If you are someone who knows what your routine is and simply want to track progress the most efficient way possible then take a look. Little features that I love:
- App can stay 'alive' (you don't have to unlock your phone every set to enter data)
- Awesome rest timing features (timer works in background, so if you flick over to check PH in your 3 min rest time it notifies you to start next set - this never works well with other apps)
- only displays enough stats that you should care about (e.g PRs, weight lifted last workout for each exercise, charts progress)

@lukedeannif Not sure I agree. Maybe for people who have trouble adhering to a routine to begin with, but I know serious lifters who track their lifts over years, even people who have been pro bodybuilders. I also know people who fall into the opposite camp (you should lift by feel) but they often weren't tracking lifts to begin with, or only were for the first year or two of lifting because they thought they had to. Personally, I lean toward the lift by feel camp, but I can see the use case (especially long-term) for this app.
